Basis Python scripting

brownie_cookie · 09-06-2011, 04:51 AM

Hi all

I'm trying to find my way in Python scripting.
I got some code from a LQ user, and i want to build on it.

I got this:

Code:

fh = open("file.txt")
for line in fh:
    if 'test' in line:
        print (line)
fh.close()

So it opens a file and searches for a word 'test', and when he finds it, he prints it, and this is working fine, BUT i get enters where i don't need them, this is my output

Code:

C:\Users\..\Dekstop>python test.py
test

test123

C:\Users\..\Desktop>

So i want to filter those enters out, but i don't know how

Does anyone know how i can filter those '123' away?

Thanks in advance and i'm trying to find it myself until someone can guide me

The problem is that the line has a return ('\r\n') on the end of it. You should be able to get it to work if you change 'print (line)' to

Code:

print line.rstrip("\r\n")

For your second question, you'll have to expand a bit - do you mean you just want to print 'test'? Because... if you're searching for test... then you know what 'test' is. If you see what I mean. Perhaps give us some more examples, and tell us which bits of the line you would want printed

Try striping off the new lines:

Code:

print (line.rstrip())

There's no need to specify "\r\n". Python (rstrip) knows how to take care of newlines

Thanks, I remembered once grail posted his solution
